The Suðuroyartunnilin (Suðuroy Tunnel) is a planned submerged fixed-link in the Faroe Islands, linking the island of Suðuroy to Sandoy. As of 2024, all vehicles and cargo, and virtually all passenger traffic must use the ferry service.

Current situation

[edit]

At present, a ferry service operates between Krambatangi on central Suðuroy and the capital Tórshavn. The ferry is operated by the national transport company Strandfaraskip Landsins and uses the vessel Smyril (passengers and cargo) taking two hours and five minutes each way. In 2019, on average 1,000 passengers (including the drivers) and 290 vehicles embarked on the ferry per day.[4] The frequency is either twice or three times per day, though the service is frequently cancelled in winter due to adverse weather and heavy seas, since the Suðuroyarfjørður strait is exposed to swell and strong tidal currents (with overfalls in places), and funnels northwesterlies.

Currently another ferry links Skúvoy and Sandoy multiple trips per day, most of which need to be reserved in advance.[5] If the Suðuroyartunnilin would route via Skúvoy, it would add Skúvoy to the road network and replace this passenger ferry service as well. The Suðuroyartunnilin would form a structural, direct link between Sandoy and Suðuroy - the two southern sýslur (districts) - for the first time in decades. Currently they are only marginally linked via a twice-weekly helicopter service, running the route Tórshavn-Skúvoy-Stóra Dímun-Froðba, which does not call at Sandoy itself.

Project

[edit]

On 8 November 2024 all Faroese political parties in the Løgting endorsed the ambition to invest in the tunnel.[6] On 11 November 2024, the Faroese government submitted the draft Suðuroyartunnilin Act for first round of hearings to the Løgting.[7] The two-lane, single-tubed tunnel will run from Skarvanes on Sandoy to Sandvík on Suðuroy. The tunnel will be 22.8 kilometers long, 9.5 meters wide, and a maximum grade of 5 promille. A total of 4 billion DKK is budgeted.[8] The tunnel would be open for traffic in circa 10 years.[9] The project will be a public enterprise, under the direct responsibility of the Løgmaður (prime minister), using the limited company p/F Suðuroyartunnilin established by the government for the purpose, while public works authority Landsverk will oversee and administrate the process.

The Act also includes related (re)construction of access roads, including a new road between the Sandoyartunnilin and central Sandoy, an upgrade of the road to Skarvanes, by-pass roads in Sandvík and Hvalba, and a new tunnel from between these villages. This new tunnel of 2.5 kilometres, replacing the current one-lane tunnel, has an estimated cost of 219 million DKK.[10][7] These side-projects are included in the overall Suðuroyartunnilin project and - except the new roads on Sandoy - the overall budget. While passing under the island of Skúvoy, the island will not be connected by the tunnel as it would increase the cost by 200-400 million DKK (but it will remain possible to add a side branch later).[11]

History

[edit]

The calls for a fixed link to Suðuroy emerged after the success of the two earliest sub-sea tunnels in the Faroe Islands, the Vágatunnilin and Norðoyatunnilin in 2002 and 2006 respectively. The Suðuroyartunnilin was first referred to officially in the National Transport Plan for 2008-2020,[12] stating no concrete ambitions.

The project was given more attention in the National Transport Plan 2012-2024, estimating an investment of 8 billion DKK for a 22.5 km tunnel from Dalur to Sandvík, but again without concrete ambitions.[13] The idea has gained more public attention since the onset of the construction of the Eysturoyartunnilin (opened in December 2020) and Sandoyartunnilin (opened in December 2023).[14][15]

The National Transport Plan for 2018-2030[16] lists the Suðuroyartunnilin again as an opportunity but no concrete plans to construct it. It recommends building the link in two sections, first from Sandoy to Skúvoy as a tunnel, bridge or causeway, and then onward to Suðuroy. It projected a costs range from 2.8 to 3.4 billion DKK, with an opening date of no earlier than 2030. The plan suggests a projected ridership of circa 1,000 vehicles per day in 2030. In 2019, Landsverk estimated ridership to be 800 motor vehicles per direction per day in 2030.[17][18][19][20]

In October 2021, public works authority Landsverk published a preliminary cost–benefit analysis scenario study that calculated the net present value for four tunnel options and two ferry options.[10][21] This report was later published in English as Removing the Island Barrier.[22] The expected ridership was now between 1,050 and 1,300 vehicles per day per direction, depending on the toll levels. The scenario study lists the following options:

Options for the link to Suðuroy
Option Project type Route Net present value Remarks
Status quo Ferry service Tórshavn (Streymoy) - Krambatangi (Suðuroy) Not included Most financially viable option. Lowest ranking in socio-economic benefits. Most CO2 emissions. The trip distance by sea is 59.3 kilometers.[23]
1. Road tunnel Skarvanes (Sandoy) - Sandvík (Suðuroy) -1.678 billion DKK
2. Road tunnel Sandur (Sandoy) - Sandvík (Suðuroy) -1.638 billion DKK
3. Road tunnel Sandur (Sandoy) - Skúvoy - Sandvík (Suðuroy) -1.735 billion DKK Highest-ranking in socio-economic benefits.
4. Car shuttle train tunnel Sandur (Sandoy) - Sandvík (Suðuroy) -4.205 billion DKK Best option for CO2 emissions. Least financially viable option.
5. Ferry service Sandur (Sandoy) - Krambatangi (Suðuroy) +72 million DKK Closely following option 0. as the most financially viable option. The trip distance by sea would be 38.3 kilometres while the added distance by road measures 25 kilometers (using the Sandoyartunnilin to Tórshavn).[23]

The total investment cost of a tunnel, excluding connecting roads would range from 3.6 to 5.4 billion DKK, corresponding roughly to one-quarter of the Faroese gross national income.[24] At most 10% of the total costs could be recovered via tolls. Projected daily ridership for both directions combined ranges from 1,060 (option 5) to 1,370 motor vehicles per day (option 3).[10] Parameters included in the analysis were operational costs, write-off (ferry Smyril), substitution effects, user prices (tolls or ferry tickets), demographic effects, employment effects, inflation and increase of wages, carbon dioxide emissions (during construction and operation) and the volume of debris generated in tunnel construction. As for option 5, the cost-benefit analysis did not consider the move of Suðuroy's ferry terminal northwards to Hvalba, which would further reduce the distance to 29.6 kilometres. It would, however, add 11 kilometers by road from Krambatangi.[25]

In November 2022, the Faroese government agreed to go ahead with the project by establishing a limited company (p/F Suðuroyartunnilin) as a fund for budget deposits and later pay the contracter.[26] The results are to be expected in autumn 2024.[27] Only after this, a final decision for the project can be expected. In the meantime, the government will put up the business plan and the sustainability assessment. In January 2023, the minister of Fisheries and Transport Dennis Holm suggested that drilling could already start within two years.[28] However, public company enterprises are part of the Prime Minister's responsibility, who referred to the coalition agreement, which does not state a start and end date.[27] [29]

On Sandoy, the Sandoyartunnilin opened in December 2023 and connects Sandoy to Streymoy. This tunnel would act as a stepping stone for Suðuroy-bound traffic. In the meantime, the ferry MS Smyril may dock in Sandur instead of Tórshavn, and sail to Hvalba, as was expressed as a possibility by Strandfaraskip Landsins in 2023.[30] This would reduce the crossing time to 1 hour and 15 minutes, thus allowing for increased frequency, and bringing travel times from Suðuroy to Tórshavn to a maximum of 2.5 hours from door to door. However, the ports in Hvalba and Sandur would need to be extended in order to accommodate MS Smyril or different large vessels.[31]

Landsverk constructed a new Hvalbiartunnil between Trongisvágur and Hvalba. This tunnel replaced the old tunnel from 1963. The old Hvalbiartunnilin was a bottleneck that needed to be solved for before Suðuroyartunnilin could become a reality.
